Application filed .une 29,

To all whom it may concern:

Be it known that I, DOLPH Il. InAHM, a citizen oi' the United States ofAmerica, residing at the city oi St. Louis, in the State oi Missouri,have invented certain new and use- 'ul Improvements in Lantern-Burners,oi which the following is a i'ull, clear, and exact description,reference being had to the accompanying drawings, forming part oi thisspecification.

Illy invention relates to a lantern burner Vl'or use in coal-oil burninglanterns and it has for its object the production oi a burner for use inthe hind of lanterns mentioned, frein which a steady ilarne can besecured and a burner that so protects the ilaine as to preventextinguislunent thereoiFV in the swinging oil the lantern -l'or thepurpose ol' Giving signals, as lor instance those eonnnoniy given. inthe use ol hand carried railroad lanterns.

Figure I is atop or plan viewY oi iuy iniproved burner partly brohenaway. Fig. II is aside elevation oi the burner partly in section. Fig.III is a vertical cross section taken on line III-III, Fig. I the bodybeing shown in elevation. Fig` IV is a side elevation oi'a inodirpiediorin of burner. Fig. V is a view of the burner shown in Fig. IV partlyin eleva tion and partly in vertical section taken on line IVI-II, IV. Y

In the accompanying drawings: l designates a wiely tube and 2 the bodyof iny burner in which the wich tube is litted. The body 2 is providedat its upper end with an outwardly flaring annular rini 3 that serves todeflect upwardly inoving air currents away i'roin the upper end ol thewiel; tube which extends above the body oi' the burner. rIhe wiel; tubehas secured to its upper end an air controlling housing` through whichair is delivered to the wich and 'flame burning thereironi in the use ofthe burner in a inanner to supply the necessary oxygen to the flamewithout there being any liability oi' the delivery oi` a current of airto the lanie ol' sutilcient strength to extinguish such i'laine. The aircontrolling housing carried by the wich tube embodies the followingelements.

4 is a wing plate receiving and attached at its center to the wick tubenear its upper end and provided with downwardly extending and spreadinginner wings 5 containing slots or air passageways 6 and also with outerupwardly extending and converging irnperiorate wings 7 separated tronithe Patented Aug. 17, 1909.

linner wings to provide air ducts lor the ascent of air at each side oithe wick tubo aliter it has passed through the slots or air passage-ways6. The outer wings 7 extend upwardly to points adjacent to the top ofthe wich tube and they are suihciently spaced apart lroin the wiclr tubeat such points to provide 'lor the access oi the ascending currents otair to the wiel; that protrudes above the wick tube during the use ofthe burner. The outer wings 7 are 1)rovided at their upper ends withvertical guards 8 located at the sides oi the wick tube and projecting'upwardly beyond the top ol" said wich tube. the necessary combustionand to prevent the passage oi strong currents of air i1nn1ediatelyacross the top ol the wich tube and the upper end ot the will; toobviate the such currents ot air. To provide tor the ieeding oi air tothe l'larne at the location oi the guards, I produce thereinpertorations 9, see 7Eig. III, through which the necessary air may passgradually to inix with the air that ascends in the air passages betweenthe inner and outer housing wings 5 and 7 after gaining access theretothrough the slots or air passageways 6 in said inner wings. At the endsot the guards S are out-turned lips I0 that extend troni the side edgesoi the wich tube and by their presence serve to strengthen a llanieburnin(r iroin a wich in the wich tube, inasniuch as when they beconieheated they causY such Haine to be drawn outwardly to the lips.

The air controlling housing of niy burner is preierably closed at itsends by end plates l1, thereby rendering it necessar f that all airsupplied through the housing by upward passage therein inust enter thehousing through the slots or passageways 6 at the bottoni oi" thehousing. The end plates just mentioned may, however, be omitted with theresult oi producing a inodiiied forni oi burner illustrated in Iligs. IVand V which correspond in other particulars to the burner I have hereinpreviously described.

For the purpose of holding the air controlling housing oi my burnerrigidly to the wick tube oi the burner and to brace the parts thereof, Iapply to the wick tube a stay or brace trarne that is secured to the aircontrolling housing. This traine coinrIhe guards 8 serve to create rlikelihood oi a ilaine being extinguished by prises a pair ot wires 13located at the sides ol the Wiclrtube and having` eyes at their endswhich receive stay Wires 14. These stay Wires and the wires 13 areconnected to the Wicktuoe by solder or other suitable means and the stayWires extend outvardly from the Wick tulee and then upwardly around theOuter Wings 7 of the air controllingl housing to which Wings they aresecured by seating,l them in sockets 15 carried by the Wings. The outerand upper ends ot' the stay Wires are preterahly permanently and rigidlyattached to the sockets just inentioned by applying solder to the wiresand sockets.
